Board Hearing : December 12, 2002 CALIFORNIA REFUELING EMISSION STANDARDS AND TEST PROCEDURES

FOR 2001 AND SUBSEQUENT MODEL MOTOR VEHICLE S The provisions of Title 40, Code of Federal Regulations (CFR), Part 86, Subparts B (as adopted or amended by the U.S. Environmental Protection Agency (U.S. EPA) on the date listed) and S (as adopted on May 4, 1999 , or as last amended on such other date set forth next to the 40 CFR Part 86 section title listed below ) to the extent they pertain to the testing and compliance of vehicle refueling emissions for passenger cars, light-duty trucks and medium-duty vehicles, are hereby adopted as the “California Refueling Emission Standards and Test Procedures for 2001 and Subsequent Model Motor Vehicles” with the following exceptions and additions. Subpart S Requirements I. General Certification Requirements for Refueling Emissions A. Applicability 1. Thes e refueling standards and test procedures are applicable to all new 2001 and subsequent model gasoline -fueled , alcohol -fueled , diesel -fueled , liquefied petroleum gas-fueled, natural gas-fueled, and hybrid electric passenger cars, light-duty trucks and medium-duty vehicles with a gross vehicle weight rating of less than 8,501 lbs. Gaseous fueled vehicles are exempt from meeting these refueling standards. In cases where a provision applies only to a certain vehicle group based on its model year, vehicle class, motor fuel, engine type, or other distinguishing characteristics, the limited applicability is cited in the appropriate section or paragraph. 2. For general certification purposes, the requirements set forth in the ”California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles” shall apply, except as otherwise noted in these test procedures. 3. Reference to vehicle sales throughout the United States shall mean vehi cle sales in California, except when certifying to the refueling standards, in which case, vehicle sales shall mean throughout the United States. 4. A small volume manufacturer is defined as any vehicle manufacturer with California actual sales less than or equal to 4500 new vehicles per model year based on the average number of vehicles sold by the manufacturer in the previous three consecutive years.As Amended : September 5, 2003

Board Hearing : December 12, 2002 2 5. Regulations concerning U.S. EPA hearings, inspections, specific language on the Certificate of Conformity, alternative useful life, and selective enforcement audit shall not be applicable to these procedures, except where specifically noted. 6. In those instances where testing conditions or parameters are not practical or feasible for vehicles certified to the refueling standards, the manufacturer shall provide a test plan that provides equal or greater confidence in comparison to these test refueling procedures. The test plan must be approved in advance by the Executive Officer. 7. The term “[no c hange]” means that these test procedures do not modify the applicable federal requirement. 8. The specifications for the fuel used in testing are set forth in 40 CFR §86.113-94 (February 18, 2000). California certification fuel is not allowed for certification or in-use testing. B. Definitions, Acronyms These test procedures incorporate by reference the definitions set forth in the Code of Federal Regulations and the definitions as set forth in the “California Exhaust EmissionStandards and Test Procedures for 2001 and Subsequent Model Passenger Cars, LightDuty Trucks and Medium-Duty Vehicles.” C. Useful Life 1. Delete §86.1805-01; §86.1805-04 and replace with: “Useful life” shall have the same meaning as provided in Title 13, CCR, §2112. D. On-Board Diagnostics 1. Delete §86.1806 and replace with: The “Malfunction and Diagnostic System Requirements for 1994 and Subsequent Model-Year Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles and Engines” as set forth in Title 13, CCR, Section 1968 1 et seq, as applicable , is hereby incorporated by reference into this test procedure. For purposes of this test procedure, all references to evaporative system monitoring, malfunction criteria, and MIL illumination and fault code storage shall also apply to refueling systems.As Amended : September 5, 2003

Board Hearing : December 12, 2002 3 E. General Standards, increase in emissions; unsafe conditions; waivers 1. Amend § § 86.1810-01 and 86.1810-04 (July 12, 2001) as follows: 1.1 (a) through (j). [See the “California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles” or the “California Evaporative Emission Standards and Test Procedures for 2001 and Subsequent Model Motor Vehicles.”]

1.2 (k) through (n) [No change.] 1.3 (o) and (p) [n/a] 1.4 A manufacturer shall also demonstrate compliance with the fuel spillage test requirements contained in Title 13, California Code of Regulations, §2235, Specifications for Fill Pipes and Openings of Motor Vehicle Fuel Tanks, as last amended January 22, 1990, incorporated by reference herein. 2. In addition to the provisions set forth in these test procedures, the ARB reserves the authority to require testing to enforce compliance and to prevent noncompliance with the refueling emission standard. 3. Vehicles certified to the refueling emission standards set forth in Section F.2.2 below, shall not be counted in the phase-in sales percentage compliance determinations. F. Emission Standards 1. Delete 40 CFR §§86.1811 through 86.1815 (all years). 2. The maximum refueling emissions for 2001 and subsequent model gasolinefueled, alcohol-fueled, diesel-fueled, fuel-flexible, and hybrid electricpassenger cars, lightduty trucks and medium-duty vehicles with a gross vehicle weight rating less than 8,501 lbs. for the full useful life are:

2.1 For gasoline-fueled, alcohol-fueled, diesel-fueled, fuel- flexible, and hybrid electric vehicles: 0.20 grams hydrocarbons per gallon of fuel dispensed. [For purposes of these test procedures, hydrocarbons shall mean organic material hydrocarbon equivalent for alcohol-fueled vehicles.] For liquefied petroleum gas-fueled vehicles : 0.15 gram hydrocarbons per gallon of fuel dispensed.

2.2 Vehicles powered by diesel fuel are not required to conduct testing to demonstrate compliance with the refueling emission standards set forth above, provided that all of the following provisions are met:

(A) The manufacturer can attest to the following evaluation: “Due to the low vapor pressure of diesel fuel and the vehicle tank temperatures, hydrocarbon vapor concentrations are low and the vehicle meets the 0.20 grams/gallon refueling emission standard without a control system.”As Amended : September 5, 2003

(B) The certification requirement described in paragraph 2.2 .(A) is provided in writing and applies for the full useful life of the vehicle. G. Durability Demonstration procedures for refueling emissions
